CLAUDE THEODORE JAMES VAUTIN, OF LONDON, ENGLAND.

METHOD OF FACING PULLEYS.

SPECIFICATION forming part of Letters Patent No. 507,467, dated. October24, 1893.

Application filed January 1 3, 1 8 9 3 To all whom it may concern.-

Be it known that I, CLAUDE THEODORE JAMES VAUTIN, residing at London,England, have invented an Improvement in Methods of Facing Pulleys, ofwhich the following is a specification.

My invention relates to an improved method of covering the peripheriesof driving pulleys or other surfaces with hardened paper, leather, orother vegetable pulp, so that the turning of the faces of the pulley orother driving drum or wheel may be dispensed with and the outer surfaceof the pulp covering affords a true surface giving a much betterfrictional grip to an ordinary driving belt than can be obtained from anordinary metal face.

My invention consists in the application of a continuous rim ofhomogeneous hard, and water-proofed pulp fiber to the periphery of apulley, drum or other mechanism and in the special method hereinafterdescribed for effecting this purpose.

In order that my invention may be the better understood I will nowdescribe the same in relation to the drawings hereunto annexed referencebeing had to the letters marked thereon.

Like letters refer to like parts in the various figures.

Figure 1 is a view of an ordinary pulley with a rim according to myinvention. Fig. 2 is a perspective view of the same. Fig. 3 is a view ofa series of pulleys or drums mounted upon a mandrel to receive the pulprim. Fig. 4 is a view of a split pulley with the pulp rim attached.

To carry my invention into efiect in the case where a new article is tobe produced I take a series of rough unturned iron pulleys, drums, orWheels A placed side by side upon a shaft B so that they will revolvetherewith and apply the pulp directly thereto to make a permanentperiphery, the pulleybeing then ready for finishing.

In order to insure the pulleys turning with the mandrel I arrange ashoulder O at one end and jamming nut D at the other end of the shaft B,so as to press the pulleys together, and against the collar 0 to form aSerial No. 458,824. (No specimens.)

drum. I then rotate the said drum in contact with a traveling felt bandcarrying a layer of prepared pulp in a similar manner as is employed inthe known manufacture of barrels, card board, 850., so that the saiddrum will take up on its surface a uniform layer of the said pulp; and Icontinue the rotation of the said drum until the pulp has accumulated toa sufifiicient thickness. The drum is then removed from contact with thetraveling felt band, and the pulp is dried, and can be treated toconsolidate the rim if necessary by rolling pressure or planishing whichwill render it hard and true. If desired, it may be subsequently turnedin alathe. The said pulp surface is then treated by soaking it in amixture of creosote or carbolic acid and a hydro-carbon such as pitch,bitumen, or asphaltu m, or with heated paraffine or ozocerite wax, or amixture of resin and resin oil; to render it waterproof and imperviousto weather, and also to increase the durability of the pulp rim. Theperiphery of the drum is then divided by a parting tool and the pulleysare withdrawn separately from the mandrel covered with a pulp surface Ewhich adheres to the under material of the rim F and are then ready foruse as far as their outer surfaces are concerned and appear as shown inFigs. 1 and 2 for example.

It is obvious that I may coat a single pulley in precisely the samemanner as a number of pulleys as hereinbefore described.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is-

1. The herein described process of making pulleys consisting in takingthe body portion or pulley proper placing the same upon a revolvingshaft and in contact with a supply of pulp .or fibrous material andthereby forming a permanent pulp periphery on the pulley body andfinally finishing the periphery while on the pulley to make a completearticle, substantially as described.

2. The herein described process of making pulleys consisting in placingtwo or more pulley bodies on a revolving shaft side by side, andabutting each other, revolving the same in contact with a supply offiber or pulp mai- In testimony whereof I have signed my terial to makea, continuous cylinder about name to this specification in the presenceof the periphery of the pulley bodies, dividing two subscribingWitnesses.

permanent; pulp peripheries, substantially as RICHARD A. HOFFMANN,
